Mousasi won the Strikeforce light heavyweight strap in 2009,
knocking out Renato
Sobral in just 60 seconds. The Iranian-born Dutchman would lose
the championship in his first defense, however, falling by
unanimous decision to Muhammed
Lawal in April of last year.

After fighting Keith
Jardine to a draw at Strikeforce “Diaz vs. Daley” in April, the
26 -year-old most recently defended his Dream title for the first
time, knocking out Hiroshi
Izumi on July 16.

St. Preux has been perfect in his Strikeforce career thus far. The
28-year-old former University of Tennessee linebacker has not lost
since 2009, rattling off eight-straight victories -- five of which
came in the Strikeforce cage.

The Haitian-American fought a total of six times in 2010, and St.
Preux closed out last year with wins over Antwain
Britt and Benji Radach
on Nov. 19 and Dec. 4, respectively.

The light heavyweight then returned to the cage only four weeks
later to outpoint Ron Humphrey
on Jan. 7. Most recently, St. Preux forced Joe Cason to
submit to punches on July 22 at Strikeforce Challengers 17.
